有色金属行业含铊废水治理技术及工业应用

Technology of thallium-containing wastewater treatment in the nonferrous metals industry and its industrial application

在含铊有色金属矿产资源开发过程中,未经有效处理的矿山酸性废水和冶炼厂的烟尘沉降等均会导致大量铊进入环境,对人类及生态环境造成严重威胁。对铊污染物相关的国家和地方标准、含铊废水治理技术及工业应用进行了详细阐述,并对有色金属行业铊污染物治理发展方向进行了展望。有色金属行业应从源头控制、过程监管、末端治理和完善的铊污染应急处置预案等方面采取积极措施,减少铊污染。

During the development of thallium-containing nonferrous metal mineral resources, the mine acid wastewater and smelter dust settlement that has not been effectively treated will lead to a large amount of thallium entering the environment, posing a serious threat to human beings and the ecological environment.In this paper, the national and local standards related to thallium pollutants, the technology for thallium-containing wastewater treatment, and its industry application are described in detail, and the development direction of thallium pollutant treatment in the nonferrous metals industry is predicted.The nonferrous metals industry should take active measures to mitigate thallium pollution from the aspects of source control, process supervision, terminal treatment, and accomplished emergency response plans for thallium pollution.
